High-Resolution Measurements of Mercury’s Surface Composition with the MESSENGER X-Ray Spectrometer
We present updates to major-element maps of Mercury using low-orbit observations from MESSENGER’s X-Ray Spectrometer.

Volatile Abundances in Apollo 12 Red Volcanic Glass
A12 red volcanic glass, together with other glass groups, show shifts in S/Dy at constant F/Nd that may be a signature of degassing of the lunar magma ocean.
Monday, 16 March 2015 @ 3 p.m., Lunar Volatiles
Large Variations in the Volatile Content of Olivine-Hosted Melt Inclusions from Lunar Magmas
New volatile analyses of lunar melt inclusions from A17 orange glass extend the range to higher Cl, F, and S contents, and first document their C contents
Tuesday, 17 March 2015 @ 6 p.m., Poster Session I: Isotope Geochemistry: Origins of Isotope Heterogeneities
Supernova Shock Triggering and Radioisotope Injection into the Presolar Cloud: Effects of Rotational Axis Orientation
Three-dimensional models of presolar clouds rotating perpendicular to shock front direction are consistent with the supernova triggering and radioisotope injection hypothesis.
Wednesday, 18 March 2015 @ 9:15 a.m., Presolar, Interplantary and Cometary Dust
Correlation Between Raman Peak Shifts and Isotopic Compositions of Sub-Micron Presolar SiC Grains
We report a positive correlation between the SiC Raman peak positions and the 12C/13C ratios for 11 submicrometer to micrometer-sized mainstream presolar 3C-SiC grains.

Are Radicals the Carriers of D in IOM?
We do not observe the expected correlations between D/H and radical concentration, determined by EPR, if exchange with H3 + caused the D-enrichments in IOM.

Organic Matter in the Unique Carbonaceous Chondrite Miller Range 07687: A Coordinated In Situ NanoSIMS, FIB-TEM, and XANES Study
Coordinated in situ analyses of organic matter (OM) in MIL 07687 indicate it lacks nanoglobules, unlike OM previously observed in other chondrite groups.

Miller Range 090657: A Very Pristine Renazzo-Like (CR) Carbonaceous Chondrite
We report isotopic, chemical, and mineralogical data that suggest Miller Range 090657 is one of the most pristine CR chondrites analyzed to date.
